Created attachment 1720266 [details] Screencast when the message gets triggered Description of problem: ----------------------------- Related to Bug 1885676 Currently, for selected nodes, if the aggregate CPU <30 and aggregate memory <72 GiB, the UI falls back to minimal deployment, wherein limits are reduced for the following pods a) RGW b) OSD c) MDS Even though the Warning message appears only if CPU<30 and memory<72, but the statement on the screen says ```The selected nodes do not match the OCS storage cluster recommended requirements of an aggregated 42 CPUs and 102 GiB of RAM. If the selection cannot be modified, a minimal cluster will be deployed.``` IMO, this statement is confusing, as looking at the text, it implies that minimal deployment would be triggered in all the cases when CPU<42 and memory<102. Hence, the actual trigger point and the message are a little contradictory. It would be good to refine the message to clearly state as to when the deployment : a) really falls back to minimal deployment b) minimal deployment would mean 1 OSD per node, no support for more OSD Version-Release number of selected component (if applicable): ----------------------------------------------- OCS 4.6 and OCP 4.6 and above How reproducible: ----------------- Always Steps to Reproduce: 1. Create an OCP cluster with multiple worker nodes, say 4 CPU and 16 GB memory. 2. In create storage cluster page, select minimum 3 worker nodes (more can be selected), making sure that total CPU is still less than 30 . 3. Check the warning message Actual results: --------------------- The warning message conveys minimal deployment will be used if below recommended config, but trigger is different Expected results: --------------------- Refine the statement to clearly match the actual trigger when this message surfaces. Additional info: --------------------- from KNIP >> Detect that itβs a small cluster CPU is < 30 or if aggregate memory < 72. >> highlight in the UI that this is a minimal cluster deployment that can support only 1 drives _____________________________________________] In the screenscast ------------------------ 9 nodes(matser made schedulable too), 4 CPU each = 36 CPU if all 9 nodes selected = no warning If 8 nodes selected = 8 * 4 = 32 CPu, no warning If 7 nodes selected, 7*4 = 28 CPU <required aggregate of 30 CPU - the warning message is triggered But the warning message still reads """""" The selected nodes do not match the OCS storage cluster recommended requirements of an aggregated 42 CPUs and 102 GiB of RAM. If the selection cannot be modified, a minimal cluster will be deployed """""
Setting target release to the active development branch (4.7.0). For any fixes, where required and requested, cloned BZs will be created for those release maintenance streams where appropriate once they are identified.

This should be part of the fixes done in https://bugzilla.redhat.com/show_bug.cgi?id=1886541. As since the limit is lowered hence the message should also change based on this reasoning I have updated its a description and am closing this. *** This bug has been marked as a duplicate of bug 1886541 ***
